Numeracy
- Hydrogen is 0.082 kg/cu m.
- Spicer generator batch - 0.3 kg/day production.
- Honda generator - 0.55 gal tank. 0.3 kg is about 0.3 gal fuel, so half a tank.
- Honda generator - runs 6.8 hrs at 225W output! [1]. Thus, we have storage enough for 3.4 hours of 225W. That is about good for night power. 2x this is plenty, outside of space heating and cooking.
- Spicer generator can be built for $1k. Balance of system may be $1k. Tank is $3k. + Honda Generator clone at about $500.
- Overall cost of $5.5k for 765 Whr for hydrogen.
- Compare to Compressed Air, 100Whr per $300 tank with cheapo air engine - need $2400 in tanks for compressed air, unless use regular compressor for 100 psi, + Air engine. Propane Tank ia $2700 for 1000 gal, can go up to 14 bar, as opposed to 300 cu ft for cylinder. 1000 gal to cu ft is 134 cu ft, x14 atm is 1876 cu ft - or 6 cylinders. Cylinders cost $1800 for that amount, so actually lower cost and more portable. Here it pays to have a higher efficiency air engine - if 150 W/tank - need 5 tanks to match the hydrogen route - or $1500. Air engine - $500 let's say - and compressor $500. $2500 for 750 Whr - much better than hydrogen.
- For gravity storage - take a quick look at gravity storage, with 1/4 acre or 1000 sq meters, 2 m deep, or 1 meter usable. It is 10,000 cubic meters of water, at 5 meter height (easy reach for most locations with hills) - we get MGH= 10000 cum * 1000kg/cum *10*5=500,000,000 Joules.
Current
- 1000ml/min - 1l/min - 60 l/hr - $2500 [2]. If production price is $2500, we should be able to opensource this for DIY at 1/2 the cost at worst, 50% savings from labor. But likely, we can go down to $500 for materials at $1/lb + $10/lb for exotic materials.
Mr. Spicer Version
- In Iowa - http://www.hydrogenwindinc.com/
- See Solar Hydrogen Chronicles for more info
- Production rate - 1000W for 170 l/hr of hydrogen. Matches above electrolyzer pretty much exactly.
- 170*24=4080 l/day. 4 cubic meters per day. Volume of 1000 gal propane tank is 3.8 cu m. This fills one propane tank in one day!
